we need your diagnostic trouble codes to help you, get them from an autoparts store....any one or buy a scanner on amazon for about 18 bucks~

Got some crappy fuel maybe?

accelerator sensor....where human meets computer....computer's gonna win...used to have a cable....but noooooo create a device that can send you FULL throttle into a tree, in your case seems to be giving contrary signals and your injection system is faithfully obeying every bogus command~

Try the coil packs. If one coil fails you loose two plugs. Pull one plug from each coil one at a time, place the end of the plug on metal and start the car. Observe the sparks. They should be blue and crisp, yellow wont do it. Don't touch while running it will hurt. Or get a spark tester but there is nothing like visually seeing your spark to rule it out as a cause. Sometimes these coils fail completely sometimes partially. If more than one coil is acting up it may be the ingnition module.
